Contact lenses correct refractive errors such as myopia (nearsightedness) and hyperopia (farsightedness). Today more and more people have switched to ‘contacts’ as they are popularly known and easier to use than spectacles. They also enhance facial looks.
Contact lenses are closer to natural sight than eyeglasses. They move with your eye and correct the refractive error closer to the eye to allow for a more natural field of vision. They don’t get in the way of your line of sight, like glasses can.
